Typo in the Turtle Syntax to demonstrate "Complement of a class" the Primer

Hi,

I have just noticed that the Turtle syntax demonstrating "complement of a
class" in the Primer is missing a line
"rdf:type owl:Class;"  just before  "owl:complementOf :Parent."

*The original syntax:*

:ChildlessPerson  owl:equivalentClass  [
   rdf:type            owl:Class ;
   owl:intersectionOf  ( :Person  [ owl:complementOf  :Parent ] )
 ] .


*The recommended syntax:*
*
*
:ChildlessPerson  owl:equivalentClass  [
   rdf:type            owl:Class ;
   owl:intersectionOf  ( :Person
                         [ rdf:type          owl:Class ;
                           owl:complementOf  :Parent     ]
                       )
 ] .
